Pterodroma externa One bird of this species was seen on the 19th. It was not assigned to race. Pterodroma sp. Three birds were identified only to this genus. One bird seen on the 26th was a small P. hypoleuca-sized bird. The underwings were white with little or no black bordes. The breast and belly were white. It appeared uniformly gray on the top of the head, back, and tail. The only bird I am familiar with these markings is the Black-winged Petrel, but it has the dark bordering the white on the underwings. Storm Petrel (White-rumped) Thirty-three storm petrels were recorded. Since no collecting was specific identification is not definite. Most birds appeared to be Leaches Storm 'etrels. One bird seen on 22 April had a brilliant white rump patch. This bird could have been a Harcourt's Storm Petrel. Red-tailed Tropicbird Three birds of this species were seen. White-tailed Tropicbird One bird of this species was observed.
